Okay, maybe I do need to revisit using 4K. But I do enjoy my 3D movies, and I don't have any 4K source materials at the moment, so the difference may not be that great, and will cost processing power.
I didn't know that I could display 3D content in 4K using any method. I haven't come across "Super-Sampling" so I'll have to find out what that is and how to set it, unless it is just setting the output resolution to 4K for all sources. I think my TV can support SBS 3D, but I'm not sure it would at 4K resolution. I think it is limited to 1080p.
Also, I thought all 3D Blu-rays used MVC coding and that is what had to be sent to the TV. I didn't know it could be converted to SBS on the fly, or maybe it can't be and I am reading too much into the comments above. If using SBS meant I had to rip all movies and convert to SBS MKV files, I'm probably not interested. I really want to spend time watching movies, not reprocessing them.
I would be concerned if 3D required the use of Direct 3D, as that will be disappearing in future, replaced by Open GL in MC. Or is that just for the MC GUI display, and not movie playback?
I would love to avoid DPI and resolution changes for all media and the Desktop, which would only leave frame rate switching to contend with.
Maybe I'll make some time to have a play with this, but last time I tried the changes screwed up Windows for a while. However, the discussion in this thread may help me avoid problems this time. We shall see.
